Although these specimens have not yet been fully studied, some interesting features in the skulls of labyrinthodonts have been noted. Two specimens, apparently of the same species, but of a new genus, show details of the bones of the basicranial region that have not before been observed.In most labyrinthodonts, as has been pointed out by Case,2 there is a large amount of cartilage in the walls of the brain case. In the specimens here described the lower lateral part of the brain case shows an unusual amount of ossification, which was possibly a result of old age rather than a generic feature. Details of the basicranial portion will be given in a later publication. The present paper describes . . . This content is PDF only. Please click on the PDF icon to access.
